Here is my Galaxy S8+ prototype with Dual-Camera.
What are the Dual-Camera functions/advantages? on this device.
I have Bar code on left and right screen part when Android is turn ON.
How to remove them? Any expert in samsung galaxy device?
Is it possible to install new OS (support or not dual camera) and bar code will disapear? How to?

But seriously talking, there were many two-sensors smartphones. One solutikn were provided with 3D screens for making 3D photos. While the other solution were coupled rgb sensor with grayscale sensors for better lumination catching(especially for low-light(i.e. Night) photos.
